Songar Tit
The Songar tit (''Poecile montanus songarus'') is a passerine bird in the tit family. It is the southern counterpart of the willow tit (''P. montanus''), and is usually included in it as a subspecies. It breeds in the deciduous mountain forests of southeast Kazakhstan, Kyrgyzstan and northern China. The 13 cm long Songar tit has a dark brown cap, blackish bib, rich brown upperparts, white cheeks and cinnamon buff underparts. The sexes are similar, but juveniles are somewhat duller. The most common call is a nasal ''zee, zee, zee'', but the notes of the bird evidently vary considerably The Songar tit usually excavates its own nesting hole, often in a rotten stump or in a tree, more or less decayed. Most nests examined are cups of felted material, such as fur, hair and wood chips, but feathers are sometimes used. The number of eggs is from five to six, white with small reddish spots or blotches. They feed on caterpillars, insects and seeds, much like other tits. Refere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nikolai Alekseevich Severtzov
Nikolai Alekseyevich Severtsov (; 5 November 1827 – 7 February 1885) was a Russian Exploration, explorer and natural history, naturalist. He was among the early promoters of Darwinian ideas in Russia. Life and work Severtsov was born in Khvoshchevatovo, Zemlyansky district, Voronezh, where his father Aleksey Petrovich was a retired guard officer who had served in the Patriotic War of 1812, losing an arm in the Battle of Borodino. He had become interested in natural history after reading Buffon's work as a child and going out on hunts. and studied at the Moscow University where he was influenced by Karl Rouillier who considered what Haeckel called as ecology as "general zoology". His master's dissertation was on the seasonal life of animals in Voronezh province. At the age of eighteen he came into contact with Grigory Karelin and took an interest in central Asia. In 1855 he applied for an associate professor position but failed to be appointed. In 1857, he joined a mission t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Felted
A felted material is a hairy or Wikt:filamentous, filamentous (hairy-like) fibre that is densely packed or tangled, forming felt or felt-like structures. Advantages of felted tissue The dermis is described in Gray's Anatomy as "felted connective tissue, with a varying amount of elastic fibers and numerous blood vessels, lymphatics, and nerves." When describing the external coat of an artery (the ''Tunica externa (vessels), tunica adventitia''), Gray said that it "...consists mainly of fine and closely felted bundles of white connective tissue..." In such classes of connective tissue the felted structure helps with resistance to tearing by distributing localised Stress (mechanics), stresses, and it imparts Shock (mechanics), shock absorption and Elastic modulus, elasticity in two or three dimensions at once regardless of the shape of the tissue. In other words, certain types of felting can yield controllable isotropy or anisotropy in the behaviour of a structure. Zoology Mamm ...

Birds Of Central Asia
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have furth ...

Poecile
''Poecile'' is a genus of birds in the tit (bird), tit family Paridae. It contains 15 species, which are scattered across North America, Europe and Asia; the North American species are the chickadees. In the past, most authorities retained ''Poecile'' as a subgenus within the genus ''Parus'', but treatment as a distinct genus, initiated by the American Ornithologists Union, is now widely accepted. This is supported by mtDNA cytochrome b, cytochrome ''b'' sequence analysis. The genus ''Poecile'' was erected by the German naturalist Johann Jakob Kaup in 1829. The type species was subsequently designated as the marsh tit (''Poecile palustris'') by English zoologist George Robert Gray in 1842. The name ''Poecile'' is from Ancient Greek ''poikilos'' "colourful". A related word ''poikilidos'' denoted an unidentified small bird. It has traditionally been treated as feminine (giving name endings such as ''cincta''); however, this was not specified by the original genus author Johann Jak ...

Handbook Of The Birds Of The World
The ''Handbook of the Birds of the World'' (HBW) is a multi-volume series produced by the Spanish publishing house Lynx Edicions in partnership with BirdLife International. It is the first handbook to cover every known living species of bird. The series was edited by Josep del Hoyo, Andrew Elliott, Jordi Sargatal and David A. Christie. All 16 volumes have been published. For the first time an animal class will have all the species illustrated and treated in detail in a single work. This has not been done before for any other group in the animal kingdom. Material in each volume is grouped first by family, with an introductory article on each family; this is followed by individual species accounts (taxonomy, subspecies and distribution, descriptive notes, habitat, food and feeding, breeding, movements, status and conservation, bibliography). In addition, all volumes except the first and second contain an essay on a particular ornithological theme. More than 200 renowned sp ...

Insect
Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs.

Caterpillar
Caterpillars ( ) are the larval stage of members of the order Lepidoptera (the insect order comprising butterflies and moths). As with most common names, the application of the word is arbitrary, since the larvae of sawflies (suborder Symphyta) are commonly called caterpillars as well. Both lepidopteran and symphytan larvae have eruciform body shapes. Caterpillars of most species eat plant material ( often leaves), but not all; some (about 1%) eat insects, and some are even cannibalistic. Some feed on other animal products. For example, clothes moths feed on wool, and horn moths feed on the hooves and horns of dead ungulates. Caterpillars are typically voracious feeders and many of them are among the most serious of agricultural pests. In fact, many moth species are best known in their caterpillar stages because of the damage they cause to fruits and other agricultural produce, whereas the moths are obscure and do no direct harm. Conversely, various species of ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feather
Feathers are epidermal growths that form a distinctive outer covering, or plumage, on both avian (bird) and some non-avian dinosaurs and other archosaurs. They are the most complex integumentary structures found in vertebrates and an example of a complex evolutionary novelty. They are among the characteristics that distinguish the extant birds from other living groups. Although feathers cover most of the bird's body, they arise only from certain well-defined tracts on the skin. They aid in flight, thermal insulation, and waterproofing. In addition, coloration helps in communication and protection. The study of feathers is called plumology (or plumage science). People use feathers in many ways that are practical, cultural, and religious. Feathers are both soft and excellent at trapping heat; thus, they are sometimes used in high-class bedding, especially pillows, blankets, and mattresses. They are also used as filling for winter clothing and outdoor bedding, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Passerine
A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped') which includes more than half of all bird species. Sometimes known as perching birds, passerines generally have an anisodactyl arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest order of birds and one of the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al.
